  • Title: Fluctuations and entropy driven space--time intermittency in Navier--Stokes fluids

  • Abstract: We analyze the physical meaning of fluctuations of the phase space contraction rate, that we also call entropy creation rate, and its observability in space--time intermittency phenomena. For concreteness we consider a Navier--Stokes fluid.
